There are many IBAN validation Libraries available on Internet. Out of all the, most reliable/official online check is available here http://www.tbg5-finance.org/?ibancheck.shtml . The JS source code is available for download
and can be embedded in any web page to validate IBAN check. But the source code is written only to use it in webpages and not as a web service.

I created this HTTP web service by modifying the existing source code, instead of rewriting from scratch. The Source code contains an HTTP Web Server which i wrote to serve the HTTP web service.

Please see the documentation for more details.

How to use the web service ?

Example :-

http://localhost:8888/?iban=AL47212110090000000235698741

Wanted to Host in IIS ?

Current Status of the Project:
